Specification of Letters Patent.

. Patented July 3, 1917.

Application filed March 20, 1912. Serial No. 684,928.

To all whom it may concern:

Be it known that I, WILLiAM GORDON lVIALLOY, a subject of the King of Great Britain, residing at Toronto, Ontario, Canada, have invented certain new and useful Improvements in Roll-Retaining Devices for Machines for Operating on Shoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skllled in the art to which it appertains to make and use the same.

The present invention relates to machines for operating on shoes, and more particularly to a roll retaining device, for holding the work supporting or other roll on its supporting stud.

Various machines employed in the manu facture of shoes are provided with a work support or other roll rotatably mounted on a supporting stud in the machine. It is often desirable for certain reasons to remove the roll fromits supporting stand.

The primary object of the present invention is to provide a roll retaining device for machines for operating on shoes which may be placed in position to retain the roll and which may be operated to permit the removal of the 'roll more quickly and easily than the devices heretofore in use. With the above object in view, a feature of the invention contemplates the provision in a machine for operating on shoes having a work supporting or other roll mounted on a roll supporting stud of a spring actuated member arranged tospring into position to engage the roll and retain it on its supporting stud when the roll is placed in operating position on its stud, and to be moved out of retaining position with relation to the roll to permit the removal of the roll from its stud. In the preferred form of the invention the roll retaining member consists of a spring plate rigidly attached to the frame which supports the roll and provided with a free extremity projecting into position to engage the lower end of the roll when the roll is placed in position onits stud.

The invention will be readily understood from an inspection of the accompanying drawings, in which Figure 1 is aside elevation of a portion of a rounding and channeling machine embodying the invention in its preferred form; Fig. 2 is a detail front elevation of the slide upon which the work supporting roll and channeling knife are mounted; and Fig. 3 is a section taken on the line 33 of Fig. 2 looking in the direction of the arrows.

The invention is illustrated in the drawing as applied to the well-known Goodyear rounding and channeling machine illustrated with substantial accuracy in the patcut to French & Meyer, No. 599,602.

- In the drawing, 1 indicates the trimming knife for trimming off the edge of the sole,

2 the crease gage, 3 the feed plate, and 4 the vertically movable slide for the channeling knife, all of which parts have the same construction and mode of operation as the corresponding parts of the Goodyear machine referred to above. A block 5 is secured by means of a screw 6 to the slide 4, and is arranged to engage the outer face of the sole at a point remote from the channeling knife to assist in supporting the sole.

The work supporting roll for engagement with the outer face of the sole to support the sole adjacent the channeling knife is indicated at 7 This roll is rotatably mounted upon a stud 8 projecting downwardly from a plate 9 secured to the upper portion of the slide 4:. The channeling knife is indicated at 10, the shank of the knife being arranged horizontally and the edge of the knife extending vertically from the shank portion beyond the face of the work supporting roll 7 The channeling knife .is secured to the plate 9rby means of a clamping block 11 which is received in a slot cut in one side of the upper end of the stud 8 and which is held in place by means of a clamping screw 12 passing through the stud 8 and screwing into the block. The clamping block is provided with an upwardly projecting portion which forms a shoulder between which and the edge of the plate 9 the shank of the knife is clamped, the shoulder being provided with a notch to receive the shank of the knife. The knife is thus securely clamped in adjusted position, and the upper face of the plate 9 is left free and unobstructed so as to permit the trimming knife to move close to the upper face of said plate and adjacent the channeling knife.

In the machine above described it is necessary to remove the work supporting roll 7 from its supporting stud to permit the knife to be removed or adjusted. It is therefore desirable that the roll be readily removable from its supporting stud, and in order to hold the work supporting roll 7 in operating position on its supporting stud 8, and at the same time permit it to be easily and quickly removed, a spring plate 13 is secured to the lower portion of the slide 4 between the block5 and said slide, and projects upwardly to a point adjacent the lower end of the work supporting roll 7. The upper end of the spring is provided with a portion bent at an angle to the body of the spring for engagement with the lower end of the roll. Thespring is preferably curved laterally to a slight degree to give it rigidity and to form a forward concave face to assist in centering the roll with relation to the stud when the roll is placed on the stud. In the drawings the spring is illustrated in the position which it assumes when the work supporting roll 7 is in operating position, the upper angularly bent end of the spring being in engagement with the lower end of the roll. When it is desired to remove the roll 7, the operator pushes the spring radially of the roll until its upper end clears the lower face of the roll. The roll may then be quickly and easily removed. When the roll 7 is replaced on the stud 8 the roll is first placed in engagement with the forward concave face of the spring, and the roll and spring are then moved back until the roll can be slipped into position on the stud. When the roll has been replaced in operating position on the stud, as shown in the drawing, the upper end of the spring snaps forward into position to engage the lower face of the roll and the roll is thereby held securely on the stud.

Although the invention has been illustrated and described as applied to a machine for rounding and channeling the soles of shoes, it is to be understood that the invention is not limited to any particular machine or class of machines for operating on shoes.

Having explained the nature and object of the invention, and specifically described one form of machine in which it may be embodied, what I claim is 1. A machine for operating on shoes, having, in combination, a removable work engaging roll, a supporting stud for the roll, and a spring actuated retaining device for the roll arranged to spring into roll retaining position when the roll is placed in operating position on the stud and to be moved out of roll retaining position to permit the roll to be removed from the stud.-

2. A machine for operating on shoes, hav ing, in combination, a removable work engaging roll, a stud supporting said roll, and a spring actuated retaining device for the roll arranged to spring inwardly toward the axis of the roll into roll retaining position when the roll is placed in operating position on the stud, and to be moved outwardly away fro the axis of the roll out of retaining position with relation to the roll to permit the roll to be removed from its stud,

out of roll retaining position to permit the roll to be removed from its stud, substantially as described.

. 4. A machine for operating on shoes, having, in combination, a roll, a stud supporting said roll, and a spring actuated retaining member for the roll having a portion located beyond the end of the stud so as to be engaged by the roll and moved out of retaining position when the roll is placed on its supporting stud, and to spring into retaining position when the roll is located in operating position on the stud, substantially as described.

5. A machine for operating on shoes, having, in combination, a roll, a stud on which the roll is mounted, and a spring actuated retaining member for the roll having a portion located beyond the end of the roll so as to be engaged by the roll when the roll is being placed in operating position on its stud and constructed to assist in centering the roll with relation to the stud, substantially as described.

(3. A machine for operating on shoes, having, in combination, a roll, a stud on which the roll is mounted, and a spring plate having a concave portion located beyond the roll so as to be engaged by the roll when the roll is being placed in operating position on the stud for assisting the operator in centering the roll with relation to the stud, substantially as described.
